Fluxo do grupo de renormalização dos modelos-'alfa' e as álgebras de Lie contínuas
(Universidade Estadual Paulista (Unesp), 2008-08-29)
This work is basically a review of some aspect of the integrability in two dimensions discussed in the Prof. Ioannis Bakas's paper called Renormalization group flows and continual Lie algebras. The main idea is to study the ...
Holographic renormalization of scalar-tensor theories.
(Universidad de ConcepciónFacultad de Ciencias Físicas y Matemáticas.Departamento de FísicaConcepción., 2023)
Inspired by the methods of holographic renormalization with topological counterterms in pure AdS4 gravity, we extend our analysis to the case involving matter, particularly in the presence of massive scalar fields with ...
Modelo de Anderson com repulsão coulombiana nos níveis que se acoplam com o ponto quântico
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2019-12-20)
In this work, a study of the Anderson model is done for the case of a quantum dot between
two electron gases, single-electron transistor (SET), where a Coulombian repulsion term
was added at the orbitals that are directly ...

Técnica do Grupo de Renormalização Numérico (GRN) aplicada em quantum dots
(Universidade Estadual Paulista (Unesp), 2014-12-18)
In this paper, we review the technique of numerical renormalization group (NRG) originally introduced to study the properties of correlated systems. Besides the revision stage of this study, we apply the to NRG calculus ...
